With just an Arduino UNO R4 and a few lines of code, you can make that happen—no expensive GSM module required. To make Arduino send a text message to your phone without using a GSM module, you don’t ...

One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino. The 4…20 mA standard was introduced a few decades ago, to replace the existing 3 ...

Fig. 2 shows the circuit diagram of the automatic daily meal reminder system. It is built around the Arduino Uno (MOD1), RTC3231 (MOD2), SIM800L GSM module (MOD3), 16×2 LCD I2C module (MOD4), a buzzer ...
